I have recently started using Feline Pine in the last 4-6 months for my 19 year old cat. I really like it.

However, in that same time my cat's liver enzymes went sky high. The first obvious cause would be hyperthyroidism, but she got every lab for that back negative. She could still have small liver growths which are common in old age.

But after searching here at VB and the net a little, I am wondering about the litter. Many people say cedar and pine can be toxic to small animals.

My cat is only 4.5 pounds and very old with bad kidneys. So I am wondering. I am going to switch and see if her enzymes go down and report back.

Wanted to let others no so if you use it to get your cat's liver enzymes tested, too.

Any sources anyone has suitable for showing the vet, I would appreciate.

My cat has had two blood panels done. I am still awaiting the results of the second one. But she has been eating and drinking twice as much as normal and her weight is dropping. In the first blood panel, her liver enzymes were not normal (I'm not sure what that means) and there was talk of hypertension... Hence we watched her for six months and are now awaiting the results of the second panel. How fortuitious that I discovered this possible connection. My sister told me that pine litter is toxic so when I researched on the Web, I found your 19-year-old cat's story. I rushed out to the pet store and bought World's Best (corn litter) which my sister says is very safe. I will now watch my cat to see if her eating and drinking rate subsides as well as her use of the cat box. It's horrible to think that I may have been poisoning her and that the more she had to use the box the more she was being poisoned. I hope that someone will chime in here with more evidence or some conclusive report. In the meantime, thank you for sharing your story and allowing me to share mine.

I should add that my 15-year-old cat was also put on chinese herbs yesterday. So if her condition gets better there may be some confusion as to which is the cure -- the herbs or the switch to non-toxic cat litter, or both.

I think it's much more likely that your cat isn't doing well because it is just old and has kidney failure instead of something related to the litter. 19 years old is well above average for a cat.

As far as the liver enzymes go..is that just recent, or have they been elevated for a while? liver's are hard, cuz there's so many things that can cause elevation to the values, some of which are concerning and some aren't. If she's not eating well because of the kidney disease, they can get liver elevations just from a period of inappetance. would need more info to offer thoughts on this but your vet is probably the better source anyway.

just to be thorough, what is in feline pine?

my two english cats are/were 19- and neither of them ever knew anything about feline pine- let alone ever peed on it- one just recently died following kidney troubles and what we think was probably a stroke, the other is likely on her way out with recent kidney challenges at the moment. sadly stuff like that does seem to suddenly catch up on eldery cats who have been in seemingly good health.

Thanks for your reminder about possible kidney issues. However, the blood panel showed no kidney problems. I was very relieved to get that news as I've treated cats with kidney failure before and it's heartbreaking.
Update on my 15-year-old cat: Within 3 days of removing the pine litter and putting her on the chinese herbs, her eating and drinking habits are returning to normal. The vet guessed that she was getting me up at night to eat or drink. But that has stopped now. I slept for almost 9 hours last night without interruption.
I will consider that the pine litter was not the problem. But just to be sure, I am keeping my cat on World's Best corn litter, especially as I get an excellent deal on it from my pet food store owners. I would say that anyone who is worried about their cat should take every avenue of prevention within their means. If that means changing the litter and/or following a good conventional/chinese medicine vet's recommendations, that is what I will do. I would not want to think that I either did not do enough (not removing a possible cause) or didn't try a non-invasive prescription from the vet. We live in fear of bad news about our little ones (at least I do, especially when they are indeed older) and it lifts my spirits to see her acting like a 5-year-old again. I recommend seeing a vet who is trained in chinese medicine because I have heard such wonderful reports and am not disappointed in this go-round of medical treatment.
Feline Pine is a brand name for pine litter -- both in pellets and in scoopable form.

I have heard conflicting viewpoints- many people say that Feline Pine is the safest, healthiest, most natural litter available, but other sources say that their process may not remove all of the pine oils which are harmful to cats. They do smell an awful lot like pine, which makes me think that they may still contain some aromatic oils.

If you want an alternative that is more natural and safer, I recommend Yesterday's News or a similar product. It's basically pelleted paper, and the pellets are a little smaller than the Feline Pine pellets and have no real odor. We use Yesterday's News in the cat kennels at my school, and it's very absorbent and doesn't produce dust like Feline Pine does.

i use a generic brand of corn litter. worlds best smells like cigarette butts to me and it made me want to um.... eat the catlitter.... which isn't ok- firstly, cos its bloody catlitter () and that messes with my head a lot, but also secondly cos i gave up smoking years ago and don't need the constant reminder of cigarettes.

anyway..... glad the cat seems better.

Dangers of World's Best- it is NOT the best!

Hello...World's best is NOT safe! It is made from GMO corn and is sprayed with Roundup and God knows what other pesticides and herbicides! I called them and they admitted this- there is even info on GMO-Free USA's page on Facebook. The best I have found thus far in my research is litter made from ground walnut. Some recommend straight sand from Agway or Home Depot, or Dry Stall for horses. I lost three cats to cancer- World's Best is pure poison! I have researched this for hours on end!
All the Best!
